The date when Homo erectus spread out of Africa has been
pushed back to two million years or so. If Neanderthal is
the descendant early Homo erectus colonizers, and Cro Magnon
the descendant of Homo erectus who remained in Africa, surely
that would be enough time isolated from one another for such
speciation to occur that they would not produce viable offspring.
